Pedicel 2–3 cm, sparsely hairy, soon glabrescent. Flowers 2–2.5 cm in diam. Hypanthium cupular, abaxially glabrous or subglabrous. Sepals triangular-ovate, 2–3 mm, abaxially glabrous, adaxially tomentose, margin glandular denticulate, apex acuminate. Petals white, broadly ovate, 9–10 mm, base shortly clawed, apex rounded. Stamens 20, slightly shorter than petals. Ovary (4-or)5-loculed, with 2 ovules per locule; styles (4 or)5, nearly as long as stamens, sparsely pubescent basally. Pome brown with few pale dots, ovoid or ellipsoid, 1–1.5 cm in diam., 4-or 5-loculed; fruiting pedicel 2–3.5 cm; sepals persistent. Fl. Apr, fr. Aug–Sep. 2n = 34*, 51*.
